To all 'tl/horn, it 71mg concern:

Be it knownfthat I, Josnrn Pniioocit, a citizen of the United States,residing at Savanna., in the county of Carroll and State of Illinois,have invented certain new and use-v ful Improvements in Grain-Cleaners,of which thefollowing is a speciiication.

My invention relates to grain cleaners and its objects are, to'providean apparatus of an exceedingly simple and durable construction in whichthe grain will be rapidly and thoroughly cleaned; to provide anapparatus'in which the grain will be cleanedby being subjected, while inmotion. to the action of' a current oi' air 5 to provide an apparatus inwhich thevgrain will be caused to l'low and spread out insuch a way asto'permit the'current of air to act upon it to the best advantage inorder to remove all particlesfol: dust and foreign mattei' therefrom,and to provide an apparatus which will 4automatically discharge thecleaned grain into .one receptzuwle andcoiivey the dust etc., removedtherefrom to another receptacl i, located at a difiere-nt point, withoutallowing the escape ol' any of such dust to the atmosphere while thegrain is being cleaned. These objects and other advantages which willhereinafter appear, I attain by means of the wnstruction illustrated inpreferred form in the accompanying drawings, wherein- Y Figure 1 is avertical central section ot a grain cleaner constructed in accordancewith my invention, looking in the direction indicated by the arrow (l)on iligure 2, and

Figure 2 is a similar view oi' the upper part oi the hood and itsconnections, taken at right angles to Figure I, looking in the directionindicated by the arrow (2) on said figure. i

Figure 3 1s a detail or a modified edge construction.

It cluiracteristic oi" my invention that which extends down adjacent tothe apex of the spreader and is in the present instance, as

shown in Figure 2, provided with the two feed arms 5. 'I ie grain isconducted :from the hopper 5 by means of the spout 7 whichleads to anydesired point. Provision is made lfor a draft of air through the casingby means of the fan 8 connected to the top of the hoodfl by means of thepipe 9 pro .rided with a regulating damper 10. The hood 4 has its loweredge spaced a slight distance from the up er edge of the hopper 5 toadmit the air Whc is designedto clean the grain as it passes in a thinsheet over the lower edge of the spreader.

It will be noted that the lower edge of the spreader is spaced a slightdistance above the lower edgerof the hood and that 'the upper edge ofthe hopper extends a short distance abovethe lower edge of thehood.

This construction provides a more advantageous application of the. airto the grain and the overi lapping edge of the hopper prevents anyspilling ol the grain at the juncture of the hood and hopper. Thespreader' 3 is supported from the hopper by means of the brackets Il. Inmy preterred lorin or' construction the hood hopper and spreader are allconical in shape which provides for an eifective spreading ot' thegrain, an easy conduction thereof from the hopper, and a converging ofthe dust particles in the hood to the point of outlet by the pipe 9. In-operation the grain is conducted by means or` the tubefi, 46, to thespout 5 from which it falls on the point ot' the spreader 3. As thegrain ap-y proaches the lower edge of the spreader its' surface iscorrespondinglyl increased and its thickness decreased, so that at thepoint at which the grain falls from the edge of the spreader to thehopper the layer of grain is of minimum thickness and the cnrrent of airinduced by the tan S and coming in at the air space. between the hopperand hood acts to the best advantage on such layer of grain.

Furthermore during thel progress ofthe grain down the surface of the`spreader the chaff and dust, which is lighter t an the grain, is workedsomewhat to the top, so that the air coming through the space betweenthe spreader and the hood acts upon that portion of the grajnnmostvigorously and carries practically all of such chaand dust up throughthe hood and out through the pipe 9. The provision of the converging 00dalso serves to direct the air current along the sheet of grain from thebottom edge nearly to the point of the spreader thereby spoilt 5 asshown has its lower end placed c ose to the point of the s reader toprevent .the air current `from iiiteriering with the fall of the grainon to the point of the spreader, but it is obvious that this arrangementcan be modified by spacing the end of the spout up a distance from theioint, in which case the ascending currents oi' air would cleen thegrain to a certain extent,.but at the same time tend to prevent thestream of grain from flowing as freely as in my preferred arrangementshown.

Figure 3 shows a modification in the lower edge of the hood 4. Thismodification consists in making the lower edge vertical as Shown at 12.llie grain falls in a sheet parallel to this vertical edge or band andthe air current is caused to ilow somewhat closer to i signed my nameiii the effecting a more perfect cleaning. Thel 1. In combination,a'casing comprising a conical hood and a hopper having their edgesslightlyseparated for the admission of air and with the edge offtjhehood below the edge of the hopper, a conical s reader having its loweredge free and slight n edge of tlie hood, means for admitting grain uponthe spreader, means for conducting it out ofthe hopper, and means fordrawing air throii h the hood.

2. 11 combination, Va casing comprising a conical hood and a hopperhaving their edges slightly separated and with the hood edge below theedffe of the hopper, a hollow conical spreader iaving its surface at anangle to that of the hood with its lower edge close to the lower edge ofthe hood but slightly above such hood edge, means for admitting grainupon the spreader, means for conducting it out of the hopper, and meansfor drawing air through the hood. l

3. In combination, a casing comprising a conical hood with a verticaledge 12 and a receiver having its edges spaced a slight distance abovethe lower extremity of theedge 12, a conical spreader having itsloweredge adjacent the upper portion ol the edge 12, means for admittinggrain u on the spreader, and means for drawing air tlirough the hood.
